May 11 (Reuters) - Wall Street moved sideways on Friday as technology stocks dipped after a six-day rally and healthcare shares rose on expectations that U.S. President Donald Trump’s speech on drug prices would largely spare the industry.

Also weighing on tech was Nvidia, which fell 1.4 percent as investors worried that a short-term surge in demand for graphics chips from cryptocurrency miners may be undermining its core business with computer gamers.

“Tech is giving back some of its gains. Market participants are not making aggressive bets after the week we’ve had, heading into the weekend,” said Keith Lerner, chief market strategist at SunTrust Advisory Services in Atlanta. “We’re in a holding pattern today, digesting the strong gains of the week that we’ve seen.”
